Huge Adamantite Weapon, cost and enhancement bonus?

[Oogar]

Well, pretty much as the topic. What do you think? If a large character wanted to have a huge Adamantite Weapon made What do you think the natural Enhancement Bonus would be? Still +2? Or maybe +3? Costs seem to be equal to the cost of a Magical weapon of the same enhancement plus 1000gp. So if you think +3 does 19,000gp seem right?

If anyone has an errata or faq that goes into this, toss me a page number, or link please. Thanks for your help.

I'd leave it as +2, but the price would depend on the weight of the weapon.
